• What is the cause and solution for SAP error message COM_IL002 - Relationship cannot be created because relationship type not reversible ?

  The SAP error message COM_IL002 indicates that a relationship cannot be created because the specified relationship type is not reversible. This typically occurs in the context of SAP's Classification and Object Management (COM) module, where relationships between objects (like materials, classes, or characteristics) are defined.
  Cause:
  The error arises when you attempt to create a relationship between two objects using a relationship type that is defined as non-reversible. In SAP, relationships can be categorized as reversible or non-reversible. A reversible relationship means that if you create a relationship from Object A to Object B, you can also create a relationship from Object B to Object A. Non-reversible relationships do not allow this bidirectional linking.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Relationship Type: Verify the relationship type you are trying to use. You can do this by navigating to the relevant configuration settings in SAP. Look for the relationship type definition in the customizing settings (usually found in the SPRO transaction under the relevant area).
  
  
  Use a Different Relationship Type: If the relationship type you are using is non-reversible, consider using a different relationship type that allows for reversible relationships, if applicable to your scenario.
  
  
  Modify Relationship Type Settings: If you have the necessary authorizations and it makes sense for your business process, you could modify the relationship type to make it reversible. This would involve changing the configuration settings in the SAP system.
  
  
  Consult Documentation: Review the SAP documentation or help files related to the specific relationship types and their characteristics. This can provide insights into which types are reversible and how they can be used.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue through the above steps, consider reaching out to SAP support or your internal SAP team for further assistance.

  Documentation: Review the SAP Help Portal for detailed information on relationship types and their configurations.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to create the desired relationship in SAP.
